All normal TOS versions and 192k EmuTOS work.

However, 256k and 512k EmuTOS versions cause WinUAE version of Hatari
to assert on startup with ST and STE emulation:

-----------------

If I enable VDI mode, then those EmuTOS versions also work.


("trace-emutos.ini" traces all EmuTOS symbols listed in emutos2.map.)
